Tesco revamps offer in UK supermarket price wars

Tesco’s existing ‘price promise’ scheme gives customers a voucher to use on future visits if their basket of goods, consisting of branded and non-branded items, could have been purchased more cheaply at its big four rivals, Wal-Mart’s Asda, Sainsbury’s, and Morrisons.
Under Tesco’s new ‘brand guarantee’ scheme, launched yesterday, if a customer’s branded grocery shop would have been cheaper elsewhere, they will automatically get the difference deducted off their bill immediately, in-store or online.
